• May 2023: The 2023 Waymo Open Dataset Challenges have concluded. Our whitepaper describing the 2023 Sim Agents challenge is on Arxiv.
  • March 2023: The 2023 Waymo Open Dataset Challenges are live. More info available here.


  • July 2022: Our paper SALVe: Semantic Alignment Verification for Floorplan Reconstruction from Sparse Panoramas has been accepted to ECCV 2022. [Project Page] [Paper]
  • March 2022: I have joined Waymo Research as a research scientist.
  • March 2022: I defended my PhD Thesis. Many thanks to Simon Lucey, Zsolt Kira, and Cedric Pradalier who joined my co-advisors, James Hays and Frank Dellaert, on my committee. The title of my thesis is “Deep Learning for Building and Validating Geometric and Semantic Maps” – coming soon to Arxiv.
  • March 2022: The Trust, but Verify (TbV) Dataset is released. This is the first public dataset for HD map change detection, an important problem for self-driving vehicle perception. Available for download here.
  • March 2022: The Argoverse 2.0 Datasets are released – featuring a Sensor Dataset (1000 scenarios w/ imagery, LiDAR, and paired HD maps), a Motion Forecasting Dataset (250K tracked scenarios w/ HD maps), and a LiDAR Dataset (20K thirty sec. scenarios, with LiDAR data and paired HD maps). Available for download here. [Devkit]
  • January 2022: An updated journal-length version of our MSeg work has been accepted to TPAMI and is now available on ArXiv here.



  • November 2020: I gave an invited talk at the ROS World 2020 virtual conference, discussing our MSeg work from CVPR. A recording is available here. Our lightweight 480p MSeg model can run at 25 fps in Pytorch.
  • August 2020: We are the runner-up in the 2020 Robust Vision Challenge (semantic segmentation track), without training on four of the seven RVC test datasets (zero-shot, cross-dataset generalization). See our talk at the ECCV 2020 RVC workshop here.
  • June 2020: Watch an excellent presentation from MachinesCanSee on our recent MSeg work, presented by Dr. Vladlen Koltun.
  • June 2020: The CVPR 2020 WAD Argoverse competitions have concluded. Congratulations to the very impressive submissions from the winners. You can watch the results presentation here, or the summary presented at ICML 2020.
  • April 2020: We are pleased to announce two Argoverse Competitions at the CVPR 2020 Workshop on Autonomous Driving. Argo AI is offering $5,000 in prizes for Motion Forecasting and 3D tracking methods. I’ve open-sourced my 3d tracking code that is currently 1st place on the leaderboard. Please consider participating! The competitions will remain open until June 10, 2020.
  • April 2020: Our MSeg paper has been accepted to CVPR 2020 and took first place on WildDash. Pretrained models available here, data available here, and a Colab to try our demo on your own images and videos.
